gimple-match: Add a gimple_extract_op function

code_helper and gimple_match_op seem like generally useful ways
of summing up a gimple_assign or gimple_call (or gimple_cond).
This patch adds a gimple_extract_op function that can be used
for that.

gcc/
	* gimple-match.h (code_helper): Add functions for querying whether
	the code represents an internal_fn or a built_in_function.
	Provide explicit conversion operators for both cases.
	(gimple_extract_op): Declare.
	* gimple-match-head.c (gimple_extract): New function, extracted from...
	(gimple_simplify): ...here.
	(gimple_extract_op): New function.
